Abstract

Apparatus and methods for providing controlled pressure-flow pulses which purge a catheter system with turbulent flow flushing. Accomplishment of such controlled pressure-flow pulses is provided by a variety of inventive devices including a special plunger rod for a conventional syringe, other interactive parts for conventional syringes, an in-line catheter attachable device which automatically generates the controlled pressure-flow pulses and also single pulse, digitally operated devices.

Description

CONTINUITY

[0001] This non-provisional U.S. patent application is a continuation-in-part of a provisional U.S. Patent Application No. 61 / 192,827 filed Sep. 23, 2008, titled TURBULENT FLOW SYRINGE AND FLUID PATHWAY INSERT.FIELD OF INVENTION

[0002] This invention is associated with apparatus and methods for clearing catheter systems (e.g. IV lines) by creating controlled and consistent turbulent flushing pressure and flow within the system to purge the line of unwanted residue, and, in particular, the invention is associated with apparatus and methods for creating such turbulent flushing pressure and flow substantially independent of clinician technique.BACKGROUND AND RELATED ART

[0003] It is well known in IV care art that turbulent “start-stop” or “push-pause” flushing of IV catheters, e.g. central venous catheters, has become an accepted method for purging matter from catheters and, thereby, preventing build-up of deposits of blood, blood residue and IV drugs within a catheter. Such build...
